Despite billions of dollars spent since the 2003 US-led invasion toppled dictator Saddam Hussein, many Iraqi cities and towns are still experiencing severe power cuts and rolling blackouts.

The issue has also partly fueled this month's protests in Iraq's southern Shiite heartland, mainly in the energy-rich province of Basra.

The protests turned violent when security forces opened fire on the angry mobs attacking and burning government offices and those of and political parties. Several protesters were killed and wounded, while others were arrested.
